The status of jihaad

In Islaam, the institution of jihaad is fardh (compulsory). However, according to different circumstances, jihaad is either fardh-e-a`in (compulsory on every person) or at times fardh-e-kifaayah (compulsory on a group of people who will be able to carry it out). At times the injunction of jihaad-bis-saif (fighting) is applicable and at times the command of jihaad-bil-maal (donating and spending) is applicable. It also happens that certain people are given the command of jihaad-bis-saif and certain people are given the command of jihaad-bil-maal. On occasions it becomes necessary to defend the Islamic cause either through literature or lectures and oration. When such occasions arise, it will become fardh to engage in these activities.
